Opis:
Fifty four mould strains (32 Aspergillus and 22 Penicillium) isolated from clinical materials were tested using dilution method. Two test media were used: Yeast Nitrogen Base (YNB) and Czapek Dox (CD). The following drugs were tested: amorolfine, cyclopirox, itraconazole, and terbinafine. In the dilution method, the drugs were tested at four contrentrations: 0.1 mg/l, 1 mg/l, 10 mg/l, and 100 mg/l. No matter which medium and/or drug was used, terbinafine turned out to be most effective. The drug at a conceatration of 1 mg/l inhibited 88.9% of the strains in the CD medium. The MIC values in the YNB medium varied from 0,1 mg/l through 100 mg/1, however, 50% of the strains were inhibited at 1 mg/l or less. Itraconazole revealed a fairly good in vitro antifungal action, particularly in the CD medium: 77.8% of the strains were inhibited at 10 mg/l or less. Aspergillus fumigatus and Aspergillus flavus were most susceptible to itraconazole. The MIC values of cyclopirox amounted to 100 mg/l for all of the strains in the CD medium but not in the YNB where they varied from 1 mg/l to 100 mg/l. Amorolfine was the least effective drug. Most of the strains were inhibited at a concentration of at least 100 mg/l. The findings give evidence that the susceptibility of Aspergillus and Penicillium to the particular drugs is different, and that the results are influenced by the test medium.

Opis:
A system of differential equations for the control of tumor growth cellsin a cycle non-specific chemotherapy is analyzed. Spontaneously acquired drug resistance is taken into account by means of a mutation rate non-decreasingly dependent on time and the drug kill rate is supposed to depend on the growth rate of sensitive cells. For general tumor growth and drug kill rates the optimal treatment consists in maximizing the allowable drug concentration throughout.

Opis:
Introduction: The main protease (Mpro) and the papain-like protease (PLpro) are essential for the replication of SARS-CoV-2. Both proteases can be targets for drugs acting against SARS-CoV-2. Objective: This paper aims to investigate the in silico activity of nine xanthophylls as inhibitors of Mpro and PLpro. Methods: The structures of Mpro (PDB-ID: 6LU7) and PLpro (PDB-ID: 6W9C) were obtained from RCSB Protein Data Bank and developed with BIOVIA Discovery Studio. Active sites of proteins were performed using CASTp. For docking the PyRx was used. Pharmacokinetic parameters of ADMET were evaluated using SwissADME and pkCSM. Results: β-cryptoxanthin exhibited the highest binding energy: –7.4 kcal/mol in the active site of Mpro. In PLpro active site, the highest binding energy had canthaxanthin of –9.4 kcal/mol, astaxanthin –9.3 kcal/mol, flavoxanthin –9.2 kcal/mol and violaxanthin –9.2 kcal/mol. ADMET studies presented lower toxicity of xanthophylls in comparison to ritonavir and ivermectin. Conclusion: Our findings suggest that xanthophylls can be used as potential inhibitors against SARS-CoV-2 main protease and papain-like protease.
